All
•Convert one metric unit to another, e.g. grams to kilograms; read and interpret scales on a range of measuring instruments
•Distinguish between and estimate the size of acute, obtuse and reflex angles
Most
• Choose and use units of measurement to measure, estimate, calculate and solve problems in a range of contexts; know rough metric equivalents of imperial measures in common use, such as miles, pounds (lb) and pints
• Use bearings to specify direction
Some
• Solve problems involving measurements in a variety of contexts; convert between area measures (e.g. mm2 to cm2, cm2 to m2, and vice versa) and between volume measures (e.g. mm3 to cm3, cm3 to m3, and vice versa)
